f. Lessee and Lessor acknowledge that the rentals payable pursuant to Section 4(a) were determined based upon an assumed average annual usage by Lessee of 300 Flight Hours. Lessee and Lessor agree to negotiate in
good faith an adjustment to such rentals in the event that Lessee’s aggregate usage from the commencement of this Agreement through the end of any calendar year exceeds 120% of the product of 300 Flight Hours times the number of years elapsed
since the commencement of this Agreement. 

 5. **RETURN OF AIRCRAFT**. 

 Upon the termination of this Agreement, Lessee shall return the Aircraft to Lessor at such location in the continental United States as may be mutually
agreed upon by Lessor and Lessee, in the condition described in Appendix D. 

 The Aircraft shall be equipped and in the same configuration
as it was on delivery. All Manuals, Logs and Technical Records will be current and accurate with respect to the period of this Agreement. All modifications, alterations, and additions made to the aircraft during the Lease will be removed at
Lessee’s expense, except for those made pursuant to an Airworthiness Directive or service letter or bulletin issued by the Airframe or Engine manufacturer, and except for those designated by Lessor, with agreement of Lessee, to remain as part
of the Aircraft.
